Abstract (en)

[origin: EP0301679A2] A multiple-input power control system accepts control signals from a radiant signal transmitter 110 and from a local control 112, selects one of the signals, and provides the selected signal to a power controller 100 to control the power to a load. At least one of the control signal sources has an actuator which is movable through a range of positions, to determine the control signal provided by that source. The system finds particular utility in controlling lighting loads.
